Chapters 11-12
Speed in a given direction
What is velocity?
The energy store in chemical bonds
What is chemical energy?
The material through which a wave travels
What is a medium?
Shows how rays change direction when they strike mirrors and pass through lenses
Used to show where an electric circuit can be opened or closed
What is a switch?
The unit for measuring force
What is the Newton (N)?
Energy stored due to the shape or position of an object
What is potential energy?
A mechanical wave in which the medium vibrates parallel to the waves' motion
What is a longitudinal wave?
Light sensitive tissue that lines the back of the eyeball; allows the brain to process images
What is the retina?
An electric circuit in which charges have more than one pathway
What is a parallel circuit?
The straight line change in position from start to end
What is displacement?
A measure of the average kinetic energy of the particles in an object
What is temperature?
What is a rainbow?
An optical instrument that records and image of an object
The transfer of charges without contact
What is induction?
The acceleration of an object is directly proportional to its mass and the force applied to it
What is Newton's second law of motion?
States that absolute zero cannot be reached
What is the third law of thermodynamics?
Cyan, magenta, and yellow
What are the primary colors of pigment?
Used to correct nearsightedness
What is a concave lens?
The measure of opposition of a charge to flow
What is resistance?
The natural tendency of an object to resist changes in motion
What is inertia?
What is conudction?
A change in sound frequency caused by motion of the sound source, motion of the listener, or both
What is the Doppler effect?
An optical instrument that uses mirrors and convex lenses to collect and focus light
What is a reflecting telescope?
Area surrounding an electrically charged particle that can exert electric force
What is an electric field?
